For this event, the candidate crawls through a tunnel maze that is approximately 3 feet high, 4 feet wide, 64 feet in length, and has two 90° turns and multiple obstacles

In addition, there are two locations where the dimensions of the tunnel are reduced

Failure

If at any point the participant chooses to end the event, he/she can call out or rap sharply on the wall or ceiling and will be assisted out of the maze although doing so will result in failure of the event

Failure also will occur if the candidate requests assistance that requires the opening of the escape hatch or opening of the entrance/exit covers
